A. Khetho ea ketane
1. Lintlha tsa Kereiti:
-G70 (Mokhoa oa Lipalangoang): Tšebeliso e akaretsang, ductility e ntle.
-G80 (Lifting Chain):Matla a phahameng, a tloaelehileng bakeng sa tšireletso.
-G100:Karo-karolelano e phahameng ka ho fetisisa ea matla ho boima (sebelisa ka hardware e lumellanang).
- Kamehla bapisa ketane le kereiti ea hardware.
2. Boholo & WLL:
- Bala ka kakaretso tsitsipano e hlokahalang (ho latela melaoana e kang EN 12195-3 kapa FMCSA).
- Mohlala: 20,000 lb load e hloka ≥5,000 lbs tsitsipano ka ketane (4: 1 ntlha ea tšireletso).
- Sebelisa liketane tse nang le WLL ≥ tsitsipano e baloang (mohlala, ketane ea 5/16" G80: WLL 4,700 lbs).
B. Khetho ea Hardware
- Likopano:
Li-Ratchet Binders: Khatello e nepahetseng, ts'ebetso e sireletsehileng (e loketseng meroalo e boima).
Lever Binders: Ka potlako, empa kotsi ea ho khutlela morao (e hloka koetliso).
- Lihoko/Liphutheloana:
Grab Hooks: Hokela ho lihokelo tsa ketane.
Slip Hooks: Ankora libakeng tse tsitsitseng (mohlala, foreimi ea teraka).
Lihokelo tsa C-Hooks/Clevis: Bakeng sa li-attachments tse khethehileng (mohlala, mahlo a khoele ea tšepe).
- Lisebelisoa: Basireletsi ba moeli, li-monitor tsa tsitsipano, mahlaahlela.
C. Litlhophiso tse khethehileng tsa Mojaro
- Mechini ea Kaho (mohlala, Excavator):Liketane tsa G80 (3/8"+) tse nang le li-binders tsa ratchet;Lipina tse sireletsehileng / mabili + lintlha tsa ho khomarela; thibela motsamao wa puo.
- Likhoele tsa tšepe:Liketane tsa G100 tse nang le li-hook tsa C kapa li-chocks;Sebelisa "figure-8" ho thaepa ka leihlo la coil.
- Mabala a Sebopeho:Liketane tsa G70/G80 tse nang le mapolanka a mapolanka ho thibela ho thella;Cross-chain at angles ≥45 ° bakeng sa botsitso ba lateral.
- Liphaephe tsa Konkreite: Liphaephe tsa Chock + liketane holim'a phala ka li-angles tse 30 ° -60 °.
A. Tlhahlobo (Pele/Kamora Tšebeliso e 'ngoe le e 'ngoe)
- Lihokelo tsa Chain:Hana haeba: E otlollotsoe ≥3% ea bolelele, mapetsong, li-nicks> 10% ea bophara ba li-link, weld splatter, corrosion e matla.
- Lihoko/Lihlapi:Hana haeba: Ho sothehile, ho buleha ha 'metso> keketseho ea 15%, mapetsong, lithapo tsa tšireletso tse sieo.
- Likopano:Hana haeba: Mohele / 'mele o kobehileng, lipawl / likere tse tsofetseng, liboutu tse hlephileng, mafome ka har'a mochini oa ratchet.
- Kakaretso:Sheba hore na ha e senyehile libakeng tsa ho kopana (mohlala, moo ketane e amang mojaro);Netefatsa matshwao a WLL a balehang le ditempe tsa mophato.
B. Tsamaiso ea Tataiso
- Phetoho e Tlamang:Mapetsong afe kapa afe a bonahalang, bolelele, kapa setempe sa mophato se sa baleheng;Lihoko/mahlaahlela a kobehileng>10° ho tloha sebopehong sa mantlha;Ho roala lihokelo tsa ketane> 15% ea bophara ba mantlha.
- Tlhokomelo e Thibelang:Lubricate ratchet binders khoeli le khoeli;Tlosa li-binder ka mor'a lilemo tse ling le tse ling tse 3-5 (le haeba li ntse li le teng; liaparo tsa ka hare ha li bonahale);Tlosa liketane ka mor'a lilemo tse 5-7 tsa tšebeliso e boima (litlhahlobo tsa litokomane).
C. Litokomane
- Boloka lits'oants'o tse nang le matsatsi, lebitso la mohlahlobi, liphumano le liketso tse nkuoeng.
- Latela litekanyetso: ASME B30.9 (Slings), OSHA 1910.184, EN 12195-3
